[comp.os.msdos.programmer] MS-DOS Re-entrancy

As noted by previous posters, 'printf' is not reentrant, and shouldn't be
called from interrupt routines.  My copy of the MSC upgrade from 
version 5.0 to 5.1 lists the functions in the standard library that 
are reentrant, and I assume new copies of 5.1 and 6.0 also contain this
info.  

It would be instructive to test the entire library, or write your own as 
was suggested, but you may have an easier time looking it up.
